Fig. 13From: Ensemble learning particle swarm optimization for real-time UWB indoor localization3D indoor localization modeling. After the initial measurement, for every target, we first establish the search space based on the corresponding measured target similar to 2D configuration. The only difference is that we model the searching space in three dimensions this time, which is denoted by a green sphere. The swarm are initiated and randomly distributed in this sphereBack to article page
